First of all, I don’t know jack about sewing.
What’s the strongest thread available for me to sew with? Do people sew with fishing line? I am trying to anchor some hard foam in place and I think thread would be the most elegant solution (better than duct tape). I would like to sew it up but it needs to stand up to a lot of lateral force from people jumping on it. The only “thread” I know of that can take that kind of force is fishing line, but I figured there must be a kind of thread that’s as strong or stronger than fishing line that can be more easily sewn.
Optimally, this would also be a thread I could use around the house because all the cushions I sew up come unraveled :wally
